b. 231

composition: Op. 23, Ballade in G minor

..

In FE (→GE) there is a (cautionary?)  to e3 in the 4th quaver. This unnecessary revision (the accidental is absent in A!) most probably resulted from a misunderstanding or a mistake when correcting another error – in FE one can see here traces of removal of g3 (printed without a , necessary at this pitch). Upon seeing the octave with a  only to the bottom note, the proofreader – perhaps even Chopin – could have instinctively added the other , particularly if he were just adding flats to the L.H. part. Having realised that it is a Terzverschreibung mistake, he marked a change to the pitch of the note, which the engraver implemented by moving the notehead along with the . EE did not include the superfluous accidental.

b. 231

composition: Op. 23, Ballade in G minor

..

In A there are no accidentals to the first L.H. octave, while the  lowering a to a is only just before the 2nd crotchet. Chopin's mistake is evidenced by the  before the bottom note of the last octave in this bar, which would be irrational if the 1st octave were supposed to be A-a (naturally, the mistake is also evidenced by the logic of the chromatic bass sequence). The mistake of A was carefully corrected by FE (→GE,EE) – flats were added to the 1st octave and the consequently superfluous accidental to a in the 2nd crotchet was removed.

The presence of e1 in A is obvious; nevertheless, it seems highly likely that it was overlooked by the engraver of GE – the notehead is slightly thinner than the adjacent ones; what is more, it is misplaced, since it is directly under f1, and not to the left of it, as required by the rule (Chopin would generally write seconds in such a way all his life).

b. 231

composition: Op. 2, Variations, complete

..

In A the last two semiquavers in the parts of both hands are written down without any accidentals. Chopin's blatant oversight was corrected only by GE2 (→GE3,FESB), in which the necessary naturals and a cautionary  to e2 were added. In the main text we also add cautionary accidentals to e1 (which is absent in the editions – see the note below) and to a2.

b. 231-232

composition: Op. 49, Fantaisie in F minor

..

In A Chopin did not write flats in the 3rd triplet in each of these bars, which was repeated by FE1. In FE2 flats were added only in bar 232, while the notation is fully correct in GE and EE.
